See bug #4112 for environmental descriptions and other information. /proc/acpi/battery/BATX/state on Dell Latitude X300 fails to show the capacity of the battery, and it's discharge/charge rate. The charging state is shown correctly. Output of /proc/acpi/battery/BAT1/state without AC adapter attached: root@linkin:~; cat /proc/acpi/battery/BAT1/state present: yes capacity state: ok charging state: discharging present rate: 768 mA remaining capacity: 0 mAh present voltage: 0 mV Output with AC adapter attached: root@linkin:~; cat /proc/acpi/battery/BAT1/state present: yes capacity state: ok charging state: charged present rate: 0 mA remaining capacity: 0 mAh present voltage: 0 mV This bug is related to the #4112 BIOS bug of the X300, and can (as mentioned in that report) be fixed by editing the DSDT and compiling it into the kernel.
still an issue in 2.6.13?
